The TVTropes Trope Finder is where you can come to ask questions like "Do we have this one?" and "What's the trope about...?" Trying to rediscover a long lost show or other medium but need a little help? Head to Media Finder and try your luck there. Want to propose a new trope? You should be over at You Know, That Thing Where.
Appeal to Familial Wisdom in Chakotay's case.
We have Stereotype, As Long as It Sounds Foreign, and tropes like Hollywood Natives and Magical Native American, but do we have a trope specifically for when the foreignness of a culture is used as license to just make up it up?
^ That isn't the trope, though.
Ah. Guess not. Misread what you were asking based on the title, sorry.

Is there a trophy for a character telling another character a story where the characters clearly represent their relationship? Examples include Chakotay's "old legend" about a restless warrior and the female chieftain who he vowed to serve (Star Trek: Voyager) and Gru's bedtime story One Big Unicorn (Despicable Me).
